HOW SHOULD I APPLY NIARONIC SERUM?
You can use it both in the morning and at night.
Gently pat 3–4 drops onto the face and neck after cleansing.
If using additional serums, use them in any order you like.
We don't advise combining it with exfoliating acids like vitamin C or others. You can always use one in the morning and the other in the evening, for example.
